Several occupants of a vehicle that crashed on Interstate 275 earlier this month were not wearing seat belts or not in appropriate child restraints, including a 2-year-old girl hospitalized with serious injuries.

That's according to Lt. Mike Shaw, a Michigan State Police spokesman, who said Friday that the crash remains under investigation.

The crash occurred about 7 p.m. March 3 when the passenger-side rear tire on a northbound Ford Expedition blew out in the area of Ford Road and the driver lost control, police said. The Expedition went off the freeway, flipping onto its right side and sliding before hitting a fence, then righting itself and coming to rest on top of the fencing, police said.

Five of the Expedition's eight occupants were ejected in the crash, and a 2-year-old girl was hospitalized at Mott Children's Hospital in Ann Arbor. She was expected to recover.
